Mrs Tan put some popsicles into her cooler box for a party. Damien took 15 of
them but returned 5 popsicles into the color. Alice then took 23 of the
remaining popsicles and an additional 3 from the color. Ben then took 14 of
the remaining popsicles. There were 21 popsicles left in the cooler in the end.
How many popsicles did Mrs Tan put into the cooler box at first?
+37167 x = origianl amount
x - 1/5x + 5 after d = 4/5 x + 5 remaining
(4/5x+5) - (2/3 ( 4/5 x + 5) +3 ) = 4/15 x - 4/3 remaining after A
then Ben takes 1/4 leaving 3/4 3/4 (4/15 x - 4/3) = 21
x = originally 110
